Trachelospermum plant named ‘Selbra’

ABSTRACT

A new cultivar of  Trachelospermum jasminoides , ‘Selbra’, characterized by its unique yellow flowers, its long blooming period, and its small sized leaves.

Botanical classification: Trachelospermum jasminoides.

Varietal denomination: ‘Selbra’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Trachelospermum jasminoides and will be referred to hereafter by its cultivar name, ‘Selbra’. ‘Selbra’ is a new cultivar of star jasmine grown for use as a landscape plant.

The Inventor discovered ‘Selbra’ as a naturally occurring whole plant mutation in his garden in Neerkant, The Netherlands in June 2003. The parent plants of the new jasmine are unknown.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2003 in Neerkant, The Netherlands. The characteristics of ‘Selbra’ have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as grown outdoors in trial beds and in containers in Neerkant, The Netherlands. These attributes in combination distinguish ‘Selbra’ as a unique cultivar of star jasmine.

-   -   1. ‘Selbra’ exhibits yellow flowers.     -   2. ‘Selbra’ exhibits small sized leaves.     -   3. ‘Selbra’ exhibits a long blooming period.

‘Selbra’ is unique for its yellow flowers, all cultivars or selections of the species Trachelospermum jasminoides known to the inventor have white to creamy white flowers. ‘Selbra’ also has smaller leaves and a longer bloom period than is typically observed for plants of Trachelospermum jasminoides.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of 2 year-old plants of the new star jasmine as grown outdoors in 19 cm containers in Neerkant, The Netherlands.

The photograph in FIG. 1 illustrates the overall appearance of ‘Selbra’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers.

The photograph in FIG. 3 is a close-up view of a leaf of ‘Selbra’.

The colors in the photographs are as close as possible with the digital photography techniques utilized and the color values cited in the detailed botanical description most accurately describe the colors of the new star jasmine.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 2 year-old plants of the new star jasmine as grown outdoors in 19 cm containers in Neerkant, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
